Heintzelman, D.S. 1961. Kermadec Petrel in Pennsylvania. Wilson Bulletin 73:262-267 (PDF)

Note: In class I mentioned that the ID of Heintzelman's bird was disputed, but I may have gotten the species wrong. Heintzelman insisted it was a Kermadec, while others thought dark morph Herald Petrel (Trinidade) was more likely and consistent with the photo. Unfortunately, the key pattern on the upperside of the wings is not visible in Heintzelman's photo and the original film which supposedly showed the upperwing has been lost. While Herald (Trinidade) is now known to occur regularly in the North Atalantic, Kermadec remains unrecorded anywhere in North American waters.

The name, Trinidade Petrel (which I may have used in class), is a name which has been applied o the Atlantic supbspecies of Herald Petrel (Pterodroma arminjoniana arminjoniana). The population in the Pacific, which has in the past been considered a separate species, is Herald Petrel (Pterodroma arminjoniana heraldica).
